isa screw running "bearing 1', with a h ix of the same pitch as the one. of the cam, and is designe to move the cam an the direction of its own helix, when the ratchet wheel n is turned.

a is a. lever fulcrumed at 8 and protruding through the bottom of the locomotive or 'front car of thetrain, and is designed to engage with part h of Fig, 1 and Fig. 2, as soon as the wheels m or m, have asscd the contact plates G or G respective y.

P is a flat spring, w T h forces lever a to its original position after 1t gets out of contact from lever h.

Thsflat springs H and H,, of the contact arrangement D are also suitable to insure contact when the cars of the trains carrying the cam-and-lever arrangement are d ifier- 'entl' loaded, allowing for any difieren'ces in t e height of the top oi the car, when the carsprings are more or less compressed.

The lever c is hinged to lever t which 15 fulcrumed at u.

z is a plug arranged to stop lever 13 assoon as it has moved the ratchet wheel at one tooth.

R is a joint of lever t supported by a flat spring, to allow the lever point to jumpto its former position'over the next tooth after the ratchet wheel is turned. w When i comes in contact with h, the lever 25 will be a'ctuated'a short distance, and will turn the ratchet wheel -n one tooth, which will be held in this The click 1: is resse against the ratchet wheel 1:. by a at spring.

If, for instance, a trainis to pass-in the direction indicated b theatres? in Fig. l, a plug on the cam wi be brought under the shortpart of lever 1, before the train passes the revious switch, and the wheel m will as be orced..-downwards, and passing the of the motors bein place by the click til.

As soon as wheel r m leaves the contact plate G lever 11 will engage with h of the contabt' arrangement, the ratchet wheel n will be actuated, which will turn cam is, a plug of the cam is will be brou ht under the short part of either lever Z or as the case may be, and the device will be adjusted to properly set the switch following the one whlch the train is to ass now.

It will be -gathere from the foregoin that, in addition to the new and practice advantages ascribed to my novel device, the same works safely, and may be easil adjusted for any route a train is to take, y simply inserting plugs at the proper places in the cam, needs little attention, and will stand any usage that it may safely be subjected.
